Developed in the 1950s, steam catapults have proven exceptionally reliable. Carriers equipped with four steam catapults have been able to use at least one of them 99.5% of the time. However, there are a number of drawbacks. One group of Navy engineers wrote: "The foremost deficiency is that the catapult operates without feedback control. With no feedback, there often occurs large transients
The EMALS energy-storage system design accommodates this by drawing power from the ship during its 45-second recharge period and storing the energy kinetically using the rotors of four disk alternators; the system then releases that energy (up to 484 MJ) in 2–3 seconds.
These control problems allow Nimitz -class aircraft carrier steam-powered catapults to launch heavy aircraft, but not aircraft as light as many unmanned aerial vehicles. A system somewhat similar to EMALS, Westinghouse 's electropult, was developed in 1946 but not deployed.
The steam catapults are large, heavy, and operate without feedback control. They impart large transient loads to the airframe and are difficult and time consuming to maintain. The steam catapult is also approaching its operational limit with the present complement of naval aircraft.
The steam system is massive, inefficient (4–6% useful work), and hard to control. These control problems allow Nimitz -class aircraft carrier steam-powered catapults to launch heavy aircraft, but not aircraft as light as many unmanned aerial vehicles.
Compared to steam catapults, EMALS weighs less, occupies less space, requires less maintenance and manpower, can in theory be more reliable, recharges quicker, and uses less energy. Steam catapults, which use about 1,350 lb (610 kg) of steam per launch, have extensive mechanical, pneumatic, and hydraulic subsystems.
Design goals for the program are: 30% reduction in manning, 20% reduction in life cycle cost, 20% improvement in operational availability, and up to a 50% reduction in installed size and weight when compared to the current steam catapults.
